140kW 175 kVA Yuchai YC6A230-D30 Diesel Generator Set

Model characteristics

1.High-strength alloy cast iron engine body, forging crankshaft, and connecting rod employing the cracking technology are adpoted, which ensure high reliability after years of full verification by market.

2.Advanced and mature electronically-control common rail(BOSCH) and high-efficient turbocharged intercooled technologies are adopted, which ensure precise control of fuel-injection quality and sufficient air intake;and the full combustion and less emission of diesel engine under different load conditions are ensured.

3.The internally-cooled oil channel is adopted for piston, which effectively reduced piston temp. and ensures the long service life.

4.Requirements for generator set performance grade G3 is satisfied. 

Application Scenarios for the 14kw 175 kVA Yuchai Generator Set

The 175 kVA power range occupies a particularly versatile position in the generator market — large enough to power medium-scale commercial and industrial facilities, yet compact and cost-efficient enough to serve as a standalone standby or prime power unit for individual buildings or process lines.

Commercial Buildings & Hotels
A 175 kVA Yuchai diesel generator set is well-suited as the primary standby power source for a mid-scale hotel (80–150 rooms), office building (3,000–8,000 m²), or retail complex. The unit can maintain power to lighting, elevator systems, HVAC controls, fire safety systems, and POS/IT equipment during grid outages.

Hospitals and Healthcare Facilities
Medical facilities require standby power that starts within 10–15 seconds of mains failure and sustains continuous operation without voltage fluctuation. The YC6A230-D30's electronic governing system and the tight voltage regulation (±1% with Stamford AVR) meet the stability requirements of sensitive medical equipment including imaging systems, ventilators, and surgical lighting.

Telecommunications Infrastructure
Telecom base stations, data aggregation points, and communication relay stations require reliable prime or standby power in locations that may lack grid connection. The 175 kVA output is sufficient to serve a medium-capacity BTS installation with room for load growth.

Industrial and Manufacturing
Production lines, injection moulding machines, CNC equipment, and process heating systems in small-to-medium manufacturing facilities typically require 100–200 kVA of standby capacity. The DB-140GF fits this window precisely, with the engine's strong transient load-acceptance capability accommodating the high inrush currents of motor-driven machinery.

Construction Project Site Power
On construction sites where grid connection is pending or unavailable, the 175 kVA Yuchai generator set provides prime power for site tools, lighting, temporary offices, and welding equipment simultaneously.

Real Estate Development — Temporary Power
Multi-unit residential construction projects require reliable temporary power throughout the build cycle. The open-frame version of the DB-140GF offers the lowest capital cost for this application, with the option to upgrade to a canopy unit for urban sites with noise restrictions.

Agricultural and Irrigation Applications
Pump-driven irrigation systems in agricultural regions with unreliable grid supply use diesel generator sets of this class as prime power for the irrigation season. The YC6A's fuel efficiency and ease of field maintenance are key selection factors in agricultural applications.

FAQ

Q: What is the difference between the prime power (175 kVA) and standby power (192.5 kVA) ratings of the DB-140GF?
Prime Power (PRP) is the rating for unlimited continuous operation at variable load — the correct rating to use if the generator is your main power source or runs for extended periods. Standby Power (ESP) is the maximum output available for up to 200 hours per year in applications where utility grid power is normally present. Using a standby-rated generator as a prime power unit will shorten engine and alternator service life and may void the warranty. If in doubt, consult Dingbo's technical team with your load profile.

Q: Is the YC6A230-D30 engine emissions-compliant for import into my country?
The YC6A230-D30 meets China Non-road Stage III and Euro III equivalent emissions standards. For markets requiring Tier 4 Final (USA EPA) or EU Stage V compliance, we can offer alternative engine configurations — please specify your emissions requirement at enquiry stage.

Q: Can I order the 175 kVA Yuchai generator with a Stamford alternator and Deep Sea controller?
Yes. Alternator brand and controller type are specified independently at order stage. The DB-140GF is assembled to your exact configuration — Stamford alternator with DSE7320 controller, for example, is a standard combination we fulfil regularly.

Q: What warranty does the DB-140GF carry?
12 months or 1,000 operating hours from date of commissioning, whichever occurs first. The Yuchai engine and the alternator (Stamford / Leroy Somer / Marathon) carry their respective OEM warranty terms, which are transferable globally through the OEM's service network.

Q: What is the fuel consumption of the 175 kVA Yuchai generator at 75% load?
At 75% load (105 kW output), the YC6A230-D30 typically consumes approximately 28–30 litres of diesel per hour, depending on ambient conditions and fuel density. Full-load consumption is approximately 32–36 litres per hour. Dingbo's factory test report for each unit includes measured fuel consumption data across the load range.

Q: Can the DB-140GF operate in parallel with another generator?
Yes. Parallel synchronisation is available with the ComAp InteliGen controller or Deep Sea DSE7320/8610 controllers with appropriate synchronisation modules. Specify parallel operation at order stage so the correct controller and output circuit breaker configuration can be supplied.

Q: Do you provide after-sales spare parts support?
Yes. Dingbo stocks common consumable and wear parts for all Yuchai engines and alternators and ships globally by express air freight. For Yuchai engines specifically, parts are also available through Yuchai's own global dealer network — a significant advantage over lesser-known engine brands.
